Head coach Pete Carroll, however, is hopeful that all three will be available this week.

Carroll told KIRO Radio Friday morning that he expects Wright -- who missed the first six games this season after knee surgery -- to play on Sunday.

The veteran linebacker sat out of practice Wednesday and Thursday, but returned on a limited basis Friday.

"He got through (Friday) fine," Carroll told reporters. "We rested him for two days, really not knowing how he would go (on Thursday). We just decided to give him another day of recovery (Friday) and he did fine."

Carroll added that McDougald (knee) is "ready to go" against the Chargers, referring to his DNPs this week as rest-related. The strong safety didn't practice Wednesday and Friday, but was a limited participant on Thursday.

"Bradley didn't get injured," Carroll said. "He's just got a sore knee that he's just working through and we just want to make sure to maximize the rest."

Carson (hip) will be a game-time decision. The second-year tailback was limited in practice both Thursday and Friday.

"We just got to make sure he's OK on game day," Carroll said. "If not, we'll go with other guys and move forward. We'll see."
